I would guess that Maximum Motorsport would be the best for street use but they sure want a bunch of money for their stuff. I have heard horror stories about UPR's stuff. What's the best for street use? Is anyone using the AJE? It looks very flimsy in the photos I have seen. The Granatelli looks like the Maximum Motorsport. I have to buy some ball joints so I have pretty much decided to just do the K member with tubular control arms because they come with new ball joints. I want something that will last and that will put up with the abuse of daily driving.
